Welcome to the AltE Off Grid Calculator.
This calculator is designed to help you size a system for off-grid
use.
Start by determining the list all of your applicances that use electricity. These are items like oefrigerators, ovens, computers, stereos, lights, etc..
If you already know the Daily Watt Hours of your load,
go to Battery Bank directly.
For each appliance,
enter the number of that appliance that you own (Qty), the power it uses (Watts) and the number of hours a day (Hrs/Day) you use the item.
We have a provided a
list of common appliances and their power consumption at the bottom of the
page.
Feel free to call our Knowledgeable Sales Folks at 877-878-4060 and have them help you find the system that fits your needs.

rating and then multiply that by its voltage to approximate its wattage).
